On my Raspberry PI CM5, I plugged in HDMI before turning it on, and my screen worked fine, with the right resolution, and it worked fine when plugged in and out. But if I plug in the HDMI after I turn it on, the screen won't display. After searching, I added vc4.force_hotplug=1 to cmdline.txt, and then plug HDMI after boot to display the screen, but the resolution is not suitable. How should I solve this problem?
